Sorry I don't have the answer, but:
https://wiki.archlinux.org/index.php/Advanced_Format
shows the HDD WD20EFRX to be logical 512 and physical 4096

and
http://excess.org/article/2010/11/wd-hdd-lying-about-4k-sectors/

It seems the first partition is aligned correctly. 

Hopefully the answer isn't "you have to calculate the sector alignment 
yourself and physically enter those values."
